Abstract_ Background In the past decade much work has been done to dissect the molecular basis of the defence signalling pathway in plants known as Systemic Acquired Resistance SAR . Most of the work has been carried out in model species such as Arabidopsis with little attention paid to woody plants. However within the range of species examined components of the pathway seem to be highly conserved. In this study we attempted to identify downstream components of the SAR pathway in apple to serve as markers for its activation. Results We identified three pathogenesis related PR genes from apple PR-2 PR-5 and PR-8 which are induced in response to inoculation with the apple pathogen Erwinia amylovora but they are not induced in young apple shoots by treatment with known elicitors of
